parts of the container so that every aricle within the machine will beacted on by the water and the thorough cleansing of the contents isinsured.

' A- further ob'ect is to provide means whereby ractica ly the entirebody of water containe wardly over the contents; the projection takmgplace in successive impulses so that less v power is required to operatethe machine than would be necessary should the entire liquid contents.be thrown upwardly at one ith "the foregoing and'other objects in viewwhich will appear as the description 'p'roceedsthe invention resides inthe combination and arrangement of parts and in the' so details ofconstruction hereinafter described and clanned', it being understoodthat, with-' in the scope of what is claimed, changes in the preciseembodiment of the invention shown can be made without departing from thespmtjof the invention.

Mounted on the shaft 4 so asjto rotate therewith is a sleeve 8 on whichare provided circular disks Q'spaced apart regularly and projecting intothe trough 3.- Aprojecting blade l0 is arranged between every two disksand the blades are all'out of alignment and areal-ranged around theshaft in a spiral series. The shaftand the parts mounted thereon can berotated in an sitable manner, as by means of a beltdriven pulle 11. Inusing this machine a' quantity 0 hot water having a cleansing substancemixedv therewith is supplied to the container so that the level thereofwill be below the cleats 5. The basket 6 with the articles therein to becleaned is lowered into the container, the cover 7 is placed inposition, and

the shaft 4 is rotated 'at a high speed. This will cause the blades 10to successively project the water upwardly from the trough through thebottom of the basket 6 and over the contents of the basket, onerotationof' the shaft being suflicient to project water from the troughthroughout the length thereof. A thorough agitation of the water I isthus effected and thecontents of the basket will be efiicientlycleansed. After this operation has been completed the dirty water can bedrained from the container through a valved outlet ,12 after which-a suply of clean hot water can be placed. in th Thusthe disheswill be t orouhly e con-' tainer and the foregoing o ration repeated. athe pre-" andbylreinoving the basket t e contents dry without further treatment.

I By referring particularlyto Figure i it "will .be noted that' byhaving the bottom of.

the container inclined as at 2 each blade 10 1 will not only throw waterupwardly through that lilortion of the.basket directly over troug butwill also throw. it laterally throughout the width of the bottom 2.
